적용 범위
This standard applies to escape ropes used for single-person evacuation during building fires, consisting of ropes, safety hooks, and optionally safety belts. It is mandatory for manufacturers producing fire escape ropes for the Chinese market. It does not cover other types of escape apparatus like descent devices or escape ladders, which are regulated under different parts of the GB 21976 series.
기술 요구 사항
The standard specifies the structural and performance requirements for escape ropes. The rope must feature a core-sheath construction with a loop at one end connected to a safety hook. Key parameters include minimum diameter, length tolerances, and minimum breaking strength. The standard also sets limits on the elongation rate when subjected to a specific load percentage of the breaking strength. Safety hooks must be made of metal with a reliable locking mechanism to prevent accidental opening. If a safety belt is included, it must meet specific dimensional requirements and withstand designated tensile loads without rupture. Manufacturers must ensure that all components, including the rope, hooks, and belts, pass strict strength and deformation tests. The standard also mandates specific marking, packaging, and storage instructions to maintain product integrity, referencing GB/T 191 for packaging pictorial marks.
시험 방법
Testing involves visual inspection for structural integrity and surface quality. Dimensional measurements for length and diameter are taken using general measuring tools. Breaking strength and elongation rate are tested according to GA 494. Safety hooks and belts undergo tensile testing using a tension machine to verify they withstand specified loads without deformation or rupture.
